Dual filter attachment

thingiverse

This is an upgrade to my original (bulkier) two-way adapter. By utilizing the male and female threads from the mask and the single_passage_maxflow pieces, this dual adapter enables two of the single_passage_maxflow pieces to be attached to the main mask. https://www.thingiverse.com/thing:4241661/files <<< DISCLAIMER <<< After a day of testing it I haven't encountered any issues, but I make no guarantees. I attribute no credit for the other components. This was an adaptive work I created using existing pieces. This model has not been approved by any regulatory agency. Use it at your own risk, and only as a last resort, if you do not have any other certified protection. The recommended measures to protect yourself from infection with the coronavirus COVID-19 are as follows: • Stay home and avoid contact with other people • Avoid touching your face with your hands • Wash your hands very frequently Note: This model only includes the dual intake pipe but does not include the required filter to effectively block the spread of the virus. The effectiveness of P3 particle filters has been mentioned, and probably also HEPA 12/13, but unfortunately we do not have the means of analysis necessary to confirm this with guarantees. Again we remind you to use this model at your own risk.
